Leveraging Memristive Systems in the Construction of Digital Logic Circuits

Abstract

The recent emergence of the memristor has led to a great deal of research into the potential uses of the devices. Specifically, the innate reconfigurability of memristors can be exploited for applications ranging from multilevel memory, programmable logic, and neuromorphic computing, to name a few. In this work, memristors are explored for their potential use in dense programmable logic circuits. While much of the work is focused on Boolean logic, nontraditional styles including threshold logic and neuromorhpic computing are also considered. In addition to an analysis of the circuits themselves, computer-aided design (CAD) flows are presented which have been used to map digital logic functionality to dense complementary metal-oxide-semiconductor (CMOS)-memristive logic arrays. As exemplified through the circuits described here memristor-based digital logic holds great potential for high-density and energy-efficient computing.
